ABSTRACT:
In a method and apparatus for measuring a driving amount of a motor, relative driving amounts and absolute driving amounts are sampled in each predetermined driving amount pulse train on the basis of an origin of a motor, the relative driving amounts, coefficient and constant of at least one linear approximate equation representing the relation between the relative driving amount and the absolute driving amount are obtained from the relative driving amounts and the absolute driving amounts sampled, and the coefficient and constant obtained are preliminarily stored in a non-volatile memory.
Accordingly, the contents in the non-volatile memory are utilized at a starting time of a motor whereby the present position indication of the motor can be conducted without effecting an origin indication of the motor.
